The most significant of these estimates include: (i) the underlying cash flows and anticipated holding periods used in assessing impairment; (ii) the determination of useful lives for tangible and intangible assets; and (iii) the assessment of the collectability of receivables, including deferred rent receivables. Longer anticipated holding periods for real estate assets directly reduce the likelihood of recording an impairment loss. If there is a change in the strategy for an asset or if market conditions dictate an earlier sale date, an impairment loss may be recognized, and such loss could be material.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;"><span style="font-weight:normal;">In March 2020, the World Health Organization declared a global pandemic related to the novel coronavirus ("COVID-19"). The significance, extent and duration of the impact of COVID-19 on us and our tenants remains largely uncertain and dependent on near-term and future developments that cannot be accurately predicted at this time, such as the continued severity, duration, transmission rate and geographic spread of COVID-19, the distribution, effectiveness and willingness of people to take COVID-19 vaccines, the extent and effectiveness of the containment measures taken, and the response of the overall economy, the financial markets and the population, particularly in the area in which we operate. The ultimate adverse impact of COVID-19 is highly uncertain;</span><span style="font-weight:normal;"> however, </span><span style="font-weight:normal;">the effects of COVID-19 on us and our tenants have affected estimates used in the preparation of the underlying cash flows used in assessing our long-lived assets for impairment and the assessment of the collectability of receivables from tenants, including deferred rent receivables. We have made what we believe to be appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent these estimates differ from actual results, our consolidated financial statements may be materially affected. </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During the years ended December 31, 2021 and 2020, we recorded $1.1 million and $11.2 million of credit losses against billed rent receivables, and $19.6 million against deferred (straight-line) rent receivables during the year ended December 31, 2020. These losses were due to the effects of COVID-19, primarily from co-working and retail tenants, that were unable to pay rent while businesses were closed, not operating at full capacity or while employees continue to work from home. During 2020, we began recognizing revenue from substantially all co-working tenants and retailers except for grocers, pharmacies, essential businesses and certain national credit tenants on the cash basis of accounting. We provided rent deferrals that had been contractually due during 2020 and 2021 totaling $10.1 million, of which $4.0 million was subsequently abated and $1.2 million was collected. During 2021, revenue for the majority of these tenants continued to be recognized on the cash basis of accounting. While we have seen some improvement in performance and cash collections, our retailers and co-working tenants are still experiencing some impact from the effects of COVID-19 and may continue to experience such impact. During the fourth quarter of 2021, we received $4.5 million of business interruption insurance proceeds for COVID-19 related losses, which were included in "Interest and other income (loss), net" in our consolidated statement of operations.</p>
